The invention isillustrstcd in the scconiigure l is a p iin-.view of one forin of 1B machine with the tlssk and pattern plste removed to expose the mechanism; F1 2 is a sectionsl view taken on line 2--2 o Fig. 1.' ont Like letten refer to like parts throng the several tlgursa.

nttrn carrier A is hinged et Al to s suits le frame A. The pattern B is mounted upon the pattern carrierk in any desired manner, as by means of the pnttern plate ll'. The dssk is also mounted upon the pnt- 25 tern carrier and is provided with n suitable bottom board B. A holding piece C is hinged to theframe and en ges the bottom board so as to hold it in p a` and is provided with a handle Cl which is opposite to $0 a handle A' on the pattern carrier. The pattern carrier is provided with projecting parts A' to which are connected s rings -A said springs being connected nt tieir other ends to the frame and acting to assist in the 3F turning movement ot' the pattern carrier.

These rings are made adjustable by means of the :hres ed end pieces A' which work in threaded parte with which the springs are connected. A receivingl device or artin 40 frame D is arranged so as to receive t ie this t when turned over to the position shown in dotted lines in F' Sl. The receiving device D is provided wi a lurality of supporting arts D* each rovi with' a bearing snr- Ui4 ace for' the y sk, and adapted to'engage the bottom board thereof, said su porting par. arrnnged to move in vertice planes so l t, adwt themselves to i fularties lnthaead .tombo'ardsossto ringthe 5 parte n' s p r tion to withdraw the pattern from These su pox-tin parte as herein shown .re provi ed 'wi curved faces D which engagecurved faces on the supports D. Some means is pro- I l5 vided for `moving the supprtng parts D* bodily.

The bottom board is then placed in osition und the holdin ieee C moved to t ie position shown in n l lines. The pntterii cnrrier. together with the pattern nml think sind associated ports, is then moved to the posiporting erts each provided with e beari surface or the desk free to move lo 'tudinally independent of the rest of sui 'supirt and ndsptod to inove in vertical lanes i2 edjnut themselves to irregularities in the bottom of the flask.
